What process is a method of heat transfer but does not contribute significantly to heating the surface or atmosphere of the earth?
a) conduction
b) convection
c) insulation
d) radiation

conduction

Explanation:

Conduction is a method of heat transfer, where two objects exchange heat by touching, but does not contribute to moving heat through earth's atmosphere, because the atmosphere is so sparse it does not transmit heat through conduction effectively. Insulation is not a method of heat transfer.
